KNOTTING DEVICE FOR GRAIN-=BINDERS.

EPECIFICATION forming part of Letters Patent No. 378,815, dated February28, 1888. Application filed Septemberlfi, 1886. Serial No. 213.682. (Nomodel.)

To all whom, it may concern:

Be it known that l, WILLIAM N. WHITE- LEY, a citizen of the UnitedStates, residing at Springfield, in the county of Clark and State ofOhio, have invented certain new and useful Improvements in KnottingDevices for Grain- Binders-namely, an automatic safetyicord-fingerofwhich the following is such a full, clear, and exact description as willenable any person skilled in the art to which it pertains to constructand use the same, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to the knotting devices of that type ofgrain-binders generally known as the Appleby binder, which is shown anddescribed'in Letters Patent No. 212,420, granted to J. F. Appleby,February 18, 1879, (and since improved,) and is in the nature of animprovement on the mechanism for supporting the binding-cord previous toforming the knot.

My invention consists in providingan automatic safety cord-finger, whosefunction is to support the cord above-and outside of the billhook andstripper during theinterval in which said knotstripper and cord-guidehas moved out of its initial position when the bindingcord is severedafter forming the previous knot, so that the cord cannot pass below thebill-hook and the stripper may freely pass under the cord when movingback to its initial position.

I am aware that various devices have heretofore been adapted for thepurpose of insuring a proper position of the cord previous to its beinggrasped by the bill-hook. Some of these devices have been stationary,others movable, operating automatically. One of the latter consisted ofa finger pivoted to the knotter frame inside of the cord guide andknot-stripper, and operated from the mechanism which operates thecord-holding apparatus. In this device the cord was supported inside ofthe usual cordguide and knot-stripper, and was not in advance of thebill-hook, and the cord was therefore liable to be drawn under thebill-hook by the straws hanging over the returning cord and interlacedwith the straws of the bundle just bound and being ejected,notwithstanding the fact that the cord was supported above the bill-hookby the finger. The supporting-finger was operated by the cordlioldingmechanism, which in the construction referred to moved only during ashort interval of time, and not at the proper time to bring thesupportingfinger into action and out of the way, when required.

In my invention the cord-supporting finger is located outside of theknot-stripper and cord-guide, being pivoted upon the same cen tertherewith, and is operated from the tyerwheel shaft, by which means theabove objcctions are avoided.

In the drawings, Figure 1 is a perspective view of a knotter, showingthe safety cordfinger in the act of supporting the cord; and Fig. 2 is asimilar view of the essential parts of a knotter, showing the safetycordfinger thrown back out of the way and the cord in place, guided bythe usual cord-guide and knot-stripper.

Similar letters refer to like parts in both views.

A is the knotter-frame; B, the breastplate; O, the tyer-wheel; D, thebill-hook; E, the tucker-finger; F, the cord-guide and knotstripper; G,the cord-holding disk; 0, the t-yerwheel shaft, all constructed andarranged as usual.

Pivoted upon the same stud as the cordguide F, but in no wise connectedwith it, is the cord-supporting finger H. Pivoted in the lugs a a of theknotterframe A is the rockshaft J, having fixed upon it the arm K, whichis connected with the cord-finger H by means of the'rod L. Formed uponthe end of the rock-shaftJ is the crank-arm j, the projecting end ofwhich engages a cam-track (shown by dotted lines) formed in the cam M,which is fixed to the tyerwheel shaft 0. Upon the cam M is also formedthe inside ejector-arm, N, (only a part of which is shown.)

The operation of my invention is as follows, viz: The knotter being inthe position shown in Fig. 1 and the'needlearm (not shown) retiringafter a sheaf is bound, leaves the end of the cord between theeordholder disk G and cord-holder shoe 1?, (shown by dotted lines,) andlays the cord across the cord-finger H, as shown. The tyer-wheel G andcam M,

rotating in direction of the arrows, the incline m of the cam-track,engaging the projecting end of the bell-crank j, throws up the arm K,

which, acting through the rod L, draws back the cord-finger to theposition shown in Fig. 2, and allows the binding-cordf to drop withinthe cord-notch in the cord-guide F. The projecting end of the bell-crankj, now encountering the circular part of the cam-track from m to it,rests. The knotter has now nearly completed the next knot, when just asthe needle-arm is about to retire the incline n of the cam-trackencounters the projecting end of the bell-crank j, and again throwsforward the cord-finger H in time to support the cord as the needle-armretires, as during this interval the cord-guide and knotstripper F hasdrawn back to the position shown in Fig. 1, for the purpose of severingthe cord (by the knife 0, attached to the stripper F) and stripping theknot from the billhook, and is therefore not in position to receive andguide the cord. The circular part of the cam-track from V to W nowengages the projecting end of the bell-crankj, causing it to rest andhold the cord-finger H in position, supporting the cord until the cordof the knot already formed has been severed and the knot stripped fromthe bill'hook, when the incline m of the cam-track engages theprojecting end of the bell-crank j and again withdraws the cord-finger Hto the position shown in Fig. 2, and the foregoing operations arerepeated, and so continue at the binding of each sheaf.

Having thus described my invention, its construction,objects, and uses,and pointed out wherein it differs from the devices heretofore in use,and without wishing to be understood as confining my claims of inventionto the precise form or proportion of parts herein shown and described,so long as the principles of construction and mode of operation areessentially the same as that herein set forth, what I do claim, anddesire to secure by Letters Patent, is

motion to said finger from the tyer-wheel shaft independent of thecord-gripping and knotstripping devices, to place said finger inposition to receive and support the cord in front of the bill-hookbefore the stripper retreats, and to cause it to remain in that positionuntil the stripper returns to its initial position successively afterthe binding of each sheaf.

2. In the knotting device of a grain-binder, a pivoted cord-supportingfinger located and operated outside of the knot-stripping andcord-retaining device to furnish a support for the cord outside of saidstripper during the interval in which the stripper is out of its inttial position in stripping the knot, and consequently inoperative as acordguide.

8. In the knotting device of agrain-binder, a cord-supporting fingerpivoted to the pivotstud of the stripper, but outside of said strippercombined with means for operating said finger independent of thestripper and cordholder, as set forth, for the purpose of furnishing asupport for the cord during the interval in which the stripper is out ofits initial position in stripping the knot, and consequently inoperativeas a cord-guide.

4. In the knotting device of a grain-binder, a cordsupporting fingerlocated outside of the knot-stripper and cord-guide, and a cam tooperate the same fixed to the t-yer-wheel shaft, and having formed uponit an ejector-arm, substantially as shown and described, and for thepurpose of conveniently operating said cordfinger and assisting indischarging the bound bundle.
